Not sure I was ever really at the top of my game even when I was, well, at the top of my game.Check out the link and you will realise that even a noice can create powerful interactive data visualisations with minimal effort. In the old days we had to resort to low level efforts and use things like OpenGL, C++, Cuda and OpenCV.
Data visualisation is now a mostly solved problem which is basically a commodity task.
Mikinton claims to have worked on ICT for 35 years in which case if he/she kept at the top of his game he would have realised about Tufte and know that the visualisations he was some impressed with are not complex in this modern era.
Aside from 1999 when I had to make one of the systems I'd developed Y2K compliant, I don't think I'd cut any code since about 1992. I was more into Project Management and ICT Procurement by then, which saw me through to retirement in 2014.
